No direct pin-compatible replacement is listed in the available documentation. For production fills or repair spares, this part is sourced through independent distribution channels — quoted to order against an RFQ with availability and current pricing confirmed at quote time. ## Peripheral set and connectivity On-chip peripherals include brown-out detect, DMA, POR, PWM, and watchdog timer. The connectivity block supports I²C, IrDA, LINbus, Microwire, SPI, SSI, and UART/USART — enough for mixed-protocol industrial buses and sensor interfaces. The 8-channel 10-bit ADC covers analog inputs like potentiometers, thermistors, or current-sense resistors without an external converter.","metaTitle":"Texas Instruments LM3S1N11-IQC50-C3 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S1N11-IQC50-C3 is an obsolete Stellaris ARM Cortex-M3 MCU with 50 MHz speed, 64 KB Flash, 12K x 8 RAM, industrial temp.
